The Eunorau FAT-HS, also listed as the Hunter X8, is the full-suspension machine in Eunorau's fat-tire hunting line. Where a hardtail passes everything the ground gives it straight to the rider, this one runs an RST Guide fork with 75mm of travel and a 48mm KS-388RL rear shock on a 6061 aluminum full-suspension frame, which is what pays off over long stretches of rutted two-track with weight on the bike. Recommended rider height is 5'3" to 6'4", saddle height adjusts from 34 to 43.3 inches off the ground, and total payload capacity is 300 lbs.

Drive is a 48V 1000W Bafang M615 mid-drive rated at 160 N.m of torque. Because the motor works through the drivetrain rather than a hub, the gearing cooperates with it: a 9-speed Shimano Altus/SunRace setup with an 11-34T cassette and a 42T CNC chainring lets you trade top speed for climbing torque by shifting rather than by changing assist level. Five levels of pedal assist and a thumb throttle control delivery, and top speed is listed at 28 MPH.

The standard battery is a 48V 15Ah pack, removable with a twist of the key so it can be charged indoors, and a 14Ah or 17Ah second battery is offered. Eunorau's 80-mile range figure is specific to a particular setup: a 48V 17Ah Samsung-cell main pack paired with a 17Ah second battery, not the standard 15Ah pack on its own. Two fitment limits come with that second battery, as Eunorau states them: the 17Ah version is not compatible with the 17-inch FAT-HS, and on the 19-inch frame the rear shock must be locked out to install and use it. A US-standard 2.0A smart charger is included.

It rolls on 26 x 4.0-inch Kenda tires on black alloy rims, with hydraulic disc brakes on 180mm rotors and a motor cutoff switch built into the levers. The CDC6 LCD display sits behind waterproof connectors and includes a push mode for walking the bike uphill on foot, and a 6-60V LED headlight runs off the main battery with a taillight at the rear. At 77.1 lbs before gear, it is a two-person lift onto a vehicle rack, and assembly tools come in the box. One point on the law: the motor's 1000W nominal rating is above the 750W threshold U.S. federal law uses to define a low-speed electric bicycle, so classification falls to the states. Depending on where you ride, a machine at this power level may be treated as an electric bicycle, a moped or a motor vehicle, with registration, licensing, insurance or off-road-only restrictions attached. Checking your state and local law, and the rules of the specific roads, paths and trails you plan to use, is the rider's responsibility.

All e-bikes comes with a peace of mind

How powerful is the motor, and does it need a license or registration?
The fat-hs uses a 48v 1000w bafang m615 mid-drive motor rated at 160 n.m of torque. that nominal rating sits above the 750w threshold u.s. federal law uses for a low-speed electric bicycle, so it may not be classed as a bicycle in your state. rules on registration, licensing, insurance and off-road-only use differ from state to state, so confirm your local law before riding on public roads, bike paths or trails.
Can i add a second battery, and what range does that give?
Yes. the standard pack is 48v 15ah and a second 14ah or 17ah battery is offered as an option, with a rated range of up to 80 miles when a 17ah main pack is paired with a 17ah second battery. two limits apply: the 17ah second battery is not compatible with the 17" frame, and on the 19" frame the rear shock must be locked out to fit and use it. batteries are removable with a twist of the key so you can charge them off the bike.
How fast does it go, and how is the power delivered?
Top speed is listed at 28 mph. the bike has five levels of pedal assist plus a thumb throttle, and a 9-speed shimano altus/sunrace drivetrain with an 11-34t cassette. since the motor drives through the gears, you can trade speed for climbing torque by shifting rather than relying on assist level alone.
What rider height and payload does it support?
Recommended rider height is 5'3" to 6'4", with saddle height adjustable between 34" and 43.3" off the ground. total payload capacity is 300 lbs, covering the rider and any gear carried. the bike weighs 77.1 lbs, so loading it onto a rack or into a truck is easier with help.
Is it full suspension, and what tires and brakes does it use?
The frame is 6061 aluminum alloy with full suspension: an rst guide fork with 75mm of travel up front and a 48mm ks-388rl rear shock. tires are 26" x 4.0" kenda on black alloy rims, and braking is hydraulic disc with 180mm rotors and a motor cutoff switch built into the levers.
What comes with it, and what is the warranty?
It arrives boxed at roughly 172 x 36 x 85 cm with assembly tools and a us-standard 2.0a smart charger included, so expect some final assembly and a brake and gear check before the first ride. the cdc6 lcd display has waterproof connectors and a push mode for walking the bike uphill. coverage is a 2-year warranty, and adventure motion support can help with setup questions or missing parts.
